Application filed September 2, 191e. Serial No. 859,848.

To all liii/tom may concern.'

Be it known that we, HARRY C. WALKER and AGREE L. BOATWRIGHT, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Money-Changing Machines, of which the following is a specification.

The invention relates to coin handling machines, and more particularly to the class of money changing machines.

The primary object ofthe invention is the provision of a machine of this character wherein on the deposit of diEerent denominations of coins therein it will enable the automatic changing of such coins so that the exact amount in smaller denominations will be delivered from the machine, thus insuring the accurate changing of the money wit-hout the handling thereof by a cashier or other person.

Another object of the invention is the provision of a machine of this character wherein spurious coins will be detected and discharged from the same without possibility of the successful operation of the machine, thus preventing an unscrupulous person from rifling the machine with fraudulent intent by the use of such coins.

A further object of the invention is the provision of a machine kof this character wherein the c oins deposited therein will control mechanism which will deliver the requisite change, for instance, on the deposite of a quarter the depositor will receive therefor five nickels, and on the deposit of a dollar four quarters will be delivered to the depositor, thus obviating the necessity `of counting change, as usual.

A still further object of the invention is the provision of a machine of this character which is extremely simple in construction, reliable and efficient in operation, and inexpensive in manufacture.

With these and otherobjects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

ln the drawings: Figure 1 isa front elevation of a machine constructed in accordance with the invention. Fig. 2 is a sectional view on the line 2-2 of Fig. 1. Fig. 8 is a fragmentary sectional view on the line 3--3 of Fig. 1. Fig. i is a vertical transverse sectional view through the machine. Fig. 5 is a fragmentary vertical transverse sectional view showing in detail the trip member.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings by numerals, the money changing machine comprises a casing 5 in which are fitted a series of slidable drawers 6, each provided with a hand nib 7 at its front to permit the convenient opening and closing of the drawer. Arranged above the drawers 6 within the casing 5 is a guideway 8; disposed in alinement with the said drawers and opening through the front wall of the casing, and within each guideway is fitted a plunger 9 formed at its front end with a push stem 10 which projects beyond the front of the casing. Within each guideway S rearwardly of the plunger 9 is a slide plate 11, formed with a circular opening 12 which is of a size correspending to a coin of a predetermined denomination, the plunger 9 being fitted in one edge with a lug 13 which engages a groove 1li, the extent of which limits the throw or movement of the plunger 9. The slide plate 11 is formed in its under face with a groove 15 in which projects a lug 16, the extent of the said groove 15 limiting the movement of the slide plate in the guideway 8 within the casing. Connected to the plunger 9 is a coiled retractile spring 17, and likewise connected to the slide plate 11 is a coiled retractile spring 1S, these springs being also connected to the casing 5 and serve to automatically shift the respective plunger and slide plates forwardly toward the front of the casing. lin normal position the plate 11 is spaced from the plunger 9 and the ends adjacent to each other of the said plunger and plate are cut away to form semi-circular notches 19 which are adapted to accommodate a coin therein when delivered between the said plunger' and plate for a purpose presently described.

Fixed to the casing 5 is a top or cover plate 20 from which rises a front coin chute 21 and a rear coin cylinder 22, thel same being arranged in vertical alinement with each drawer 6 within the casing. The coin chute 21 is formed with a coin passage 23, the inlet end of which opens through the front of the chute 21, while its outlet or inner end communicates with a circular opening 24 formed in the top or cover plate 20, said opening 24C being adapted for communication "with the notches 19 when the plunger 9 and slide plate 11 are in normal position so that if a coin of a vpredetermined denomination is inserted within the passage 23 it will lgravitate therethrough and vbecome deposited within-the notches 19l to 12 inthe slide plate 11, and these coins within the cylinder 22 being of smaller denominations than the-coin to be deposited within the coin chute 21 so that when the coin is placed within the'chute and the machine operated the exact number of coins of a smaller denomination will be automatically discharged from'the machine, thus furnishing the depositor with the exact change for the coin inserted in the chute.

ProvidedY in the casing 5 rearwardly of the cylinder 22 and extending beneath the .drawer 6 is the coin discharge passage 26,

the outer end of which opens throughthe front of the casing 5 for communication vwith a trough or ledge 27, while the inner .end of the said passage 26 is adapted to register with the openingk 12 in the slide plate 11 when shifted from normal position after the insertion of a coin within the chute 21 so that the coins vof smaller denominal tions yheld within the opening 12 will graviyto tate therefrom through the passage 26 to the trough or ledge 27, thus giving change to thedepositor for the amountof the coin inserted within the chute 21. For instance, if

the notches 19 are of a size to accommodate a nickel inserted within the chute 21 and the opening l2 is of a. size to receive five pennies from thecylinder 22, it will be apparent that when the nickel has been inserted in the chute 21 and the plunger 9 has been pushed inwardly within the casing 5, the slide plate 11 will be shifted rearwardly, bringing the opening 12 into alinement with the inner end of the discharge passage 26 so that the pennies within the said opening 12 ywill' be delivered to the passage 27 from which they will gravitate therethrough into the trough or onto the ledge 27 to be received by the depositor of the nickel.

f The-respective plungers 9 and slide plates 11v are constructed so that quarters deposited within the machine will eect the delivery of five nickels, the deposit of ten cents will e'ect the delivery of two nickels, the deposit of a nickel or five cents will effect the delivery of five pennies, and the deposit of a dollar will effect the delivery of four quarters. Each cylinder 22 is of a size to accommodate coins of a predetermined denomination, that is to say, the same are arranged to receive pennies, nickels, dimes and quarters. On the deposit of a half dollar within the machine five dimes will be delivered therefrom. However, itis to be understood that the particular construction for permitting the change coins to be delivered from the machine as hereinbefore set forth does not restrict the invention in this particular, as the construction can be varied to permit the delivery of other change coins.

Leading from the passage 23 in the chute 21 and opening through the rear of the latter is a branch passage 28, while located within the passage 23 is a rocking weighted coin detector 29 which serves to detect spurious coins deposited within the chute 21, and also acts to deflect such spurious coins from the said passage 23 through the passage 28 to be discharged from the machine, so that this coin cannot be used to effect the operation of the machine for delivering change therefrom.

a Journaled in the top or cover plate 20 is a trip member 30 to which is connected a spring 31, the latter serving to hold the end a of the member 30 in the path of movement of the plunger 9, the slide plate 11 being formed with a cut away portion 32 so as not to interfere with the end a of the member 30 in its movement, while the plun- `ger 9 is formed with a recess 33 in which are arranged tripping pins 34, the latter being adapted to coact with the end l) of the member 30 so that on the,forward movement `of the plunger 9 the said member 30 will be positively rocked with the aid of the spring 31 to depress a coin held within the notches 19 in the said plunger 9 and sliding plate 11 to force the said coin through the passage 25 into the drawer 6 for the deposit of the coin within the latter.

It will be noted that when a coin is not infr Mounted transversely in the casing 5 is 1,157,826 lllt out the same, while carried by this shaft are a series of L-shaped arms 37, the same working through suitable openings 88 so as to intersect the passages 23 in the chutes 21 to hold coins deposited therein and prevent the same from falling through the outlet openings 28, yet on manipulation of the said shaft the arms can be moved so as to open the outlets 28 and thereby permit the coins to drop out of the chute or passages 23 therein. Arranged between one of the bearings on the casing and one of the arms 37 on the shaft 35, and surrounding the latter, is a coiled compression spring 39 which acts upon the shaft to shift the same in a direction to bring the arms 38 into working relation within the passagesv23 in the chute. U pon pressing upon the end of the shaft 35 without the casing the arms can be retracted out of the passages 23 for the freeing of the coins deposited therein.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.
